HINGE.

Specification of Letters Patent.

Patented Nov. 11, 1919.

Application filed June 16, 1919. Serial No. 304,458.

b all whom it may concern Be it known that I, THOMAS F. BARTA, a citizenof the Unlted States of America, re-

siding at Pisek, in the county of 'Walsh and State of North Dakota, haveinvented certain new and useful Improvements in Hinges, of which thefollowing is a specification.

The primary object of the present invention is to provide a hinge inwhich the leaf extensions bent to provide the knuckles of the hingesections are adapted to be passed through openings provided in the hingeplates with the terminal edges thereof secured beneath said plates.

With the above and other objects in view, the invention consists in thecombination and arrangement of parts herein fully described inconnection with the accompanying drawing, and in which like referencecharacters indicate similar parts throughout the several views,

In the drawing,

Figure 1 is a top plan viev of a hinge constructed in accordance withthe present invention,

Fig. 2 is a cross sectional view of the hinge and a portion of asupporting structure showing the terminal edges of the knuckles of thehinge extending through the hinge plates,

Fig. 3 is a detail perspective view of a portion of one of the hingeplates with the terminal edges of the knuckles removed from the slot inthe hinge plate, one of the knuckles being broken away to show the plateslot,

Fig. at is a cross sectional view of a portion of one of the hingeplates with the hinge pintle in dotted line positions show ing theposition of the plate knuckle be fore entering the plate slot, v

Fig. 5 is a perspective view of a portion of one of the hinged platesshowing the reversed side as disclosed in Fig. 3, i

Fig. 6 shows a modified form of the invention embodyingthe same featuresbut showing two knuckle sections in a single hinge and Fig. 7 is an edgeview of the hinge shown in Fig. 1.

Describing the invention more in detail, there is provided ahingeembodying similar leaf sections 8 having the usual openings 9 thereinarranged in any desired for mation for the reception of screws 10 orlike retaining means, the plate sections 8 being secured to the support11 shown in Fig. 2 which may be any object that is desired to hingedlyconnect parts thereof together.

The knuckle of the hinge includes leaf extensions 12 arranged in spacedrelation as shown in Fig. 3 providing alternate clearing spaces 13 forthe cooperating leaf extension 12 of the other plate section 8 so thatwhen the plate sections are united, the adjacent leaf extensions 12 arecarried by the opposite hinged plates. in Figs. 3 and 5, the extensionsare curved to substantially cylindrical form and carry tongues 14 at theterminal edges the of while the base of the sections 8 are provided withslots 15 beneath the extension 12 and through which the tongue 14: isadap ed to be extended and retained therein by 1'0. ing one face engagethe beveled edge 15 of said slot, this arrangement being more clearlyshown in Figs.v 2 and 4.

In assembling the hinged plate sections 8, the pintle 17 is insertedthrough the cooperating lmuckles 12 of the hinge as shown in Fig. 1 andthe knuckles 12 are then moved into closer relationship with said pintlewith the terminal ends or tongues 1?: projected through the plate slots15 and when. so arranged, the resiliency thereof will cause the tonguesto engage the beveled walls 16 As illustrated i of said slot to preventdisplacement of said tongues and securely hold the knuckle ext tensionsin their proper position surrounding the pintle 17. As illustrated inFig. l, the pintle 17 is retained in position in the knuckle sections bythecotter pin 18.

A modified construction of the invention is shown in Fig. 6, but all theessential elementsare present therein, it being noted that in this formof construction, there is provided a three-plate hinge embodying acentral section 19 and end. sections phi-- vided with the umial screwreceiving openings 21 while the knuckles 12 are identical to thepreferred construction, there being shown in dotted linesin this figure,tongue extension 14 upon the knuckles 12.

While I have herein shown r the preferred embodiments of my, in

tion, it will nevertheless be understood that minor changes may be madein the combination and arrangement of out departing from the spirit andscope o the invention as claimed.

What I claim is:

A butt hinge comprising a knuckle havelined wall forming one side ofsaid plate 10 slot adapted to be engaged by said extension. tongues.when the same are passed through said plate openings with the outer Wallof the slot spaced therefrom, a pintle inserted through the registeringknn'ekles and means for retaining the bolt therein.

In testimony whereof ll ail ix my signature.

THOMAS F. BARTA.
